Fisher and her mother, Reynolds, lived next door to each other for more than a decade, on a 3.5-acre property separated by a private road. Their family members are auctioning off the property, and more than 1,500 lots of Hollywood memorabilia. The memorabilia auction will be held in late September, three months before Fisher’s final film, “Star Wars: The Last Jedi,” is set to be released.

Fisher picked up a Spanish-style mansion on Coldwater Canyon Drive in 1993 for $13.75 million, Mansion Global reports. In 2000, Reynolds bought the house next door for about $1 million.

Fisher’s 4,200-square-foot, four-bedroom, four-bath home was built in 1919 and has its own Hollywood pedigree.

“King Kong” actor Robert Armstrong built the house, which was home to Bette Davis before Armstrong sold it to legendary costume designer Edith Head in 1933. Fun fact: Head was the inspiration for the character Edna Mode in Pixar’s “The Incredibles.”

In 2004 Architectural Digest described Fisher’s home as a “hip museum of a house, an ode to the obsessive joy of collecting.” Fisher showed Architectural Digest, room by room, the one-of-a-kind artwork, furniture and decorations. Many of those pieces will go on the auction block.

Fisher hosted a who’s who of Hollywood elite at her home. At one point, singer James Blunt lived in Fisher’s guesthouse and recorded a song in one of her bathrooms.
